The MTD_TEST config option was added in between the MTD_PARTITIONS config
and its dependent options which causes the resulting menu system to
display incorrectly as MTD_TEST does not depend on MTD_PARTITIONS. So
move it up a few lines where it won't cause a problem.

linux v2.6.31-rc6 can not detect NEC uPD29F064115.
uPD29F064115 is a 16 bit device.

This patch adds 4-bit ECC support for large page NAND chips using the new
ECC mode NAND_ECC_HW_OOB_FIRST. The platform data from board-dm355-evm
has been adjusted to use this mode.
The patches have been verified on DM355 device with 2KiB-page Micron
devices using mtd-tests and JFFS2. Error correction up to 4 bits has
also been verified using nandwrite/nanddump utilities.

This patch adds the new mode NAND_ECC_HW_OOB_FIRST in the nand code to
support 4-bit ECC on TI DaVinci devices with large page (up to 2KiB) NAND
chips. This ECC mode is similar to NAND_ECC_HW, with the exception of
read_page API that first reads the OOB area, reads the data in chunks,
feeds the ECC from OOB area to the ECC hw engine and perform any
correction on the data as per the ECC status reported by the engine.
"ECC_HW_OOB_FIRST" name suggested by Thomas Gleixner

This patch adds a new "page" parameter to all NAND read_page/read_page_raw
APIs. The read_page API for the new mode ECC_HW_OOB_FIRST requires the
page information to send the READOOB command and read the OOB area before
the data area.

Remove the ARM dependency from the generic "onenand" platform device
driver. This change makes the driver useful for other architectures as
well. Needed for the SuperH kfr2r09 board.
Apart from the obvious Kconfig bits, the most important change is the move
away from ARM specific includes and platform data. Together with this
change the only in-tree board code gets an update, and the driver name is
also changed gracefully break potential out of tree drivers.
The driver is also updated to allow NULL as platform data together with a
few changes to make use of resource_size() and dev_name().

orion_nand_probe lives in .init.text, so using platform_driver_register to
register it is wrong because binding a device after the init memory is
discarded (e.g. via sysfs) results in an oops.
As requested by Nicolas Pitre platform_driver_probe is used instead of
moving the probe function to .devinit.text as proposed initially. This
saves some memory, but devices registered after the driver is probed are
not bound (probably there are none) and binding via sysfs isn't possible.

The "end of a C state" trace point currently happens before
the code runs that corrects the TSC for having stopped during idle.
The result of this is that the timestamp of the end-of-C-state event
is garbage on cpus where the TSC stops during idle.
This patch moves the end point of the C state to after the timekeeping
engine of the kernel has been corrected.

If end_pfn is equal to (unsigned long)-1, then the loop will never end.
Seen on 32-bit kernel, but could have happened on 64-bit too once we get
hardware that supports 64-bit guest addresses.
Change both functions to a 'do {} while' loop with the test at the end,
and check for the PFN having wrapper round to zero.

This means we're limited to 44-bit addresses on 32-bit kernels, and
makes it sane for us to use 'unsigned long' for PFNs throughout.
Which is just as well, really, since we already do that.

Fixed hardware devices have no handles, so just pass an explicit
NULL rather than something that looks like it might be meaningful.
acpi_device_notify() doesn't need the handle anyway; the only
reason it takes it as an argument is because the acpi_notify_handler
typedef requires it.

We had two functions, acpi_os_execute_deferred() and
acpi_os_execute_hp_deferred() that differed only in that the
latter did acpi_os_wait_events_complete(NULL) before executing
the deferred function.
This patch consolidates those two functions and uses a flag in
the struct acpi_os_dpc to determine whether to do the wait.

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices. This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket. This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.

Report KEY_BRIGHTNESSUP and KEY_BRIGHTNESSDOWN input events when the
ThinkPad is in "passive brightness control" mode (because either we or
ACPI video touched _BCL), and ACPI video is not processing these
events by itself.
This happens only on Lenovo ThinkPads with ACPI video support, when
operating with the ACPI video driver in acpi_backlight=vendor mode.
Issuing these events is the right thing to do, and will work around
bugzilla #13368, if userspace is properly configured and actively
handles these events.
For other ThinkPads, and when ACPI video is handling brightness
changes, thinkpad-acpi will continue NOT sending KEY_BRIGHTNESS*
events by default.
